' INk-RIBBON-WINDING MEcHAN'rsM.

Application filed July 29,1925. Serial No. 46,823.

- sired length is wound upon each spool.

The form-of my invention hereinafter described includes means enabling the oper ator'to instantly rigidly connect such a spool with the winding mechanism and instantly disconnect the same; means arranged to stop the winding mechanism; means which may be manually adjusted and set to predetermine the length of ribbon which shall be wound before thestop mechanism is caused to automatically 'operate;-and means whereby said stop mechanism may be manually reset in operative position, after belng automatically tripped. As such winding mechanism normally operates at highspeed; I prefer to provide it with a brake mechanism which is automatically brought into operation when the stop mechanism is tripped, so as to'check the momentum of the mechanism. My invention "includes the various novel features of construction and arrangement hereinafter more definitely specified.

" In said drawings: Fig. I is a 'front elevation of a convenient embodiment of my invention, including a'fragmentary, somewhat diagrammatic, indicatlon of the means whereby the stop mechanism may be manually reset after being automatically tripped.

Fig. IX is a transverse vertical sectional view of said mechanism, taken on the line IX, IX in Fig. V in the direction of the arrows on said line.

Fig. X is a vertical sectional view of the electrically operative stop tripping device.

In said figures: l is the base frame of the winding mechanism in whichthe winding shaft 2 is journaled, preferably in ball bearings 3 and 4, as indicated in Figs. V and IX. Said winding shaft 2 has the pulley 6 rigidly connected therewith, whereby it may be rotated by the belt 7 which is arranged to be shifted on to the loose pulley 8, automatically, as hereinafter described. v

As indicated in Fig. V; said winding shaft 2 is hollow and provided with the internal screw thread; 9 at the front end thereof in which is detachably fitted the external screw thread of the spool clutch sheath member 10, best shown in Fig. VII. Said clutch member 10 has the longitudinal slot 11, best shown in Fig. 'VI, in which the clutch blade member '12 is mounted to reciprocate longitudinally and radially. As best shown in Fig. VII; said clutch member 12 has the cam inc'line 14L at the lower edge thereof which rides over the front edge of the slot in said clutch member 10, so that when said member 12 is withdrawn, to the right in Fig. VII, it is thrust radially outward, with Said clutch member 12 has the screw threaded socket 15 at its rear end for engagementwith the screw threaded front end 16 of the clutch rod 17, by which said blade 12 may be shifted longitudinally in its sheath 10. Said rod 17 is normally stressed in the direction of the arrows indicated in Figs. V and VII, by the spring 19 which abuts at one end against the case of the ball bearing 4 and at the other end against the collar 20 which is rigidly connected withsaid rod. It may be observed that movement of said clutch rod 17 in that direction thrusts the clutch blade member 12 radially outward with re-, spect to said clutch sheath member 10, to rigidly clamp the ribbon spool 22 in con nection with said winding shaft, by frictional engagement. of said clutch members 10' and 12 with the inner surface of the I. as

axial bore in the hub 23 of said spool, as indicated in Fig. V. However, said spool 22 may be instantly released from said clutch, by movement of said clutch rod 17 in the direction opposite to said arrows shown in Figs. V and. VII, and'such movement is effected by means of the yoke 25 which embraces said rod 17 between said collar and the knob 26 which is internally screw thread ed as a nut in engagement with the thread 27 on the rear end of said rod 17. As shown in Fig. V; said yoke is rigidly connected at its other end with the chain bar 28 which ismounted to reciprocate in said base frame land the bracket 29 rigidly connected with said frame, and is connected at its front end with the chain 31 which extends overthe sheave 32 to the pedal 3%, indicated in Fig. Said sheave 32 is journaled in the bracket iv connected with said 35 v which is r c.

A frame 1. It is to bd understood that downward movement of said. pedal 3st and chain 31 thrusts sa1d clutch rod 1'? forward so that the clutch blade 12 rides over the edge of I provide means to automatically stop the.

g rotation of said winding shaft2, as follows:

' bracket 40 rigidly connected with said base Said belt? passes to the pulley 6 between the tines of the belt; shifting fork 37, which is rigidly connected w th the belt shlfting lever 88 which s fulcrinnedon the screw 39 in the frame Said lever 38 carriesthe brake shoe bracket 42 which is pivotally connected connected with said bolt 46.

therewith by the screw L3 and faced with the brake shoe 4-.5 which may be formed v of [leather or other material adapted to. frictlonally engage the ad acent face of sa1d pulley 6 when said lever 38 is swung to the right in Fig. V. Such movement is conveniently effected by the spring bolt 46 which is mounted to reciprocate; in the opposite sides of said base frame 1, as indicated in Fig. V, and pivota'lly connected with said lever 38. bythe screw 47. Said bolt is encircled by the spring 49 which abuts at one .end against said frame 1 and at the other end against the collar 50 which is rigidly Said spring 49 continually tends to thrust sa1d spring bolt 46 to the right in Fig. 'V but is normally held by said belt shifting {lever 38, in the inoperative position shown in Fig. V; in which said parts are detained by the detent latch lever 52 which is fulcrumed on the screw stud 5 3 'projecting from said frame 1. Said latch 52 has the hardened hook piece 54; rigidly connected'therewith,to overhang and engage the right hand edge of said lever 38 as lndicated 1n Flg. V, when said shifting lever 38 to the right in Fig. V to shift said belt 7 from said pulley 6 to the loose pulley 8 on said winding shaft 2 so as to stop the positive rotation of the latter. However, the momentum of the parts would. cause said shaft 2 to continue to rotate if it were not for the fact that such movement of the lever presents thebrake shoe 45in contact with the 'adj acent face ofsa-id pul'ley 6 against which, it is pressed by said spring 49 tothus check and stop the rotation of said shaft 2 after said belt 7 has been. shifted. I Said detent latch 52'may beuplifted to permit said belt 7 to be shiftedand rotation of the'shaft 2 stopped, as above described,

by means of themanual trip, lever 56 which,

as indicated in Figs. V, VIII and IX,'iS fulcrumed on the screw stud 57 projecting from the outside of said base frame 1 and has its rear L-end extending below the end of said" lever 52 which projects through said base frame 1. e o M iowevjer, I also provide an electrically op erative tripping device including the casing 59/ in which thetrip lever GOis fulcrumedand from which it extends beneath the end of said latch lever :52 as. indicated in Figs. VIII and The latter tripping device in cludes an electromagnet- 61, indicated in Fig. X, having an armature 62 in operative relation with said trip lever60 so thatthe latter is normally held in the o'sition shown in Fig. VIII but is uplifted liy'its spring 63 to' strike and uplift said latch lever '52, and thus disengage the latter from said belt shifting lever-38, whenever said electromagnet 61 is energizedby closure of the circuit in which its conductors 64 and 65 are in eluded.

The ink ribbon 67 primarily wound in its a large roll, from which it passes'underneath j i the guide stud 68between the guidecollars;

69, asindicatedin Figs. I and IV. IS-aid guide stud 68 is rigidly mounted in said base frame 1 and said collars 69 are axially ad-.

justable thereon and provided with set screws TOwhere-by they may be held in adjusted position in accordance with the width of said ribbon 67 Said ribbontli' is thus directed over the roller 71'to' said ribbon spool 22 to which its front end is con-v 1 nected 111 any convenient manner so that I Fig. IV. The tension of said ribbon 67is such as to frictionally engage the ribbon with and turn said roller 71 and the measuring shaft so that the extent of the rotation of the latter corresponds'with the extent of the ribbon which is thus caused to pass over and turn said roller 71. Said measuring shaft 73 is-arranged to actuate an electric switch mechanism to close said circuit and stop said windingshaft if and when seven yards of ribbon have been wound on said spool 22 or twelve yards have. been wound thereon, dependent upon manual adjustment of the switch mechanism, and as follows:

Said measuring shaft 73 has, rigidly con v nected therewith, the worm 77 which engages the teeth on. the worm gear 78, which is mounted on the screw stud 79 pro ecting from said base frame 1 and is provided with the contact pin 80 projecting therefrom in.

theI pathof the adjustable contact arm 81;

. the latter being rigidly connected with the inner end of shaft 82 which is journaled in the insulating bearing 83 which is mounted in said base frame 1. Said shaft 82 has rig idly connected with its outer end the index arm 84 having the index pin 85 for engagement with any oneof the three seats 87, 88 and 89, indicated in Fig. III, which are in the metal plate: 90 which is also insulated from said base frame 1 by the insulating block 91 indicated in Figs. I and V. Said plate 90 has an electrical connection With said conductor 64 so that said contact arm 81 is the terminal of one side of said electrical circuit; the other side of said circuit being grounded upon said base frame 1 by way of said conductor and a'source of current 92, as indicated in Fig. V. It is to be understood that when said contact arm is manually set in the position indicated in dotted lines in Fig. IV, which corresponds with the position of the index arm 84 in which the incez-z pin 85 engages the index seat 87 as indicate'd in Fig. III; said contact pincarried by the worm gear 78 is adapted to contact with said arm 81 once during each revolution and thus close said. clrcult, ac-

tuate said trip lever 60 to release said latch lever 52 and thus stop the Winding mechanism after seven yards of ink ribbon'have been wound upon the spool 22. I

' Said measuring shaft .7 3 is also provided with the Worm 94, rigidly connected therewith, engaging-the teeth of the worm gear 95 which is provided with the contact pin 96 which projects in the path of said contact arm 81 when the latter is manually set in the position indicated in full lines in Fig. IV

which corresponds with the position of the 7 index arm 84 shown'in Fig. III; in which the index pin is engaged in the index seat 89. The construction and arrangement are then such that said stop circuit is closed once during each revolution of said worm gear which is so proportioned that one revolution thereof corresponds with the winding of twelve yards of ink ribbon upon the spool 22.

When said index arm 84 is manually set with its index pin 85 engaged with the index seat 88. indicated in Fig. III; said contact arm 81 is intermediate of the paths of the contact pins 80 and 96 aforesaid so that neither of said contact pins can reach said contactarm 81 and, consequently, in that position of said contact arm 81, the winding mechanism may be operated indefinitely without being automatically stopped as above contemplated. I find it convenient to provide said worm gear 95 with the pointer 98 which is presented in a vertical direction when the mechanism is stopped as the result of contact of the pin 96 with said contact arm 81; it being understood that such stoppage is not absolutely instantaneous, as the momentum of the mechanism is such that it continues to turn to a certain extent even after the application of the brake shoe 45 upon the pulley 6 as above described. I also find it convenient to provide the pointer 100 upon the gear wheel 101 which is mounted to turn upon the screw stud 102 projecting inwardly from said frame 1 and has its teeth in mesh with the teeth of said worm gear 78 so that said pointer 100 is presented in vertical position when the winding mechanism is stopped as the resultof closure of said circuit by contact of the pin 80 with said contact arm 81. Said pointers 98 and 100 merely facilitate the adjustment and manipulation of the winding mechanism by the operator.

In order to conveniently reset, to the normal position shown in Fig. V, said belt shiftindicated in Fig. 1. Moreover, I find it convenient to provide said tripping lever (50 with the chain 110, indicated in Fig. X, which may be connected to a separate pedal or be connected to said chain 108. as indicated in Fig. I. It is to be understood that if said chains 31, 108 and 110 are all connectedto the single pedal 34 they may be of respectively different lengths and more or less slack; so that the respective operations effected thereby may be performed during different portions of the movement of said pedal 34.
